Jia Ren took a pack of Ju Yuan Ling San and sniffed it, finding it in no way inferior to the Five Elements Spirit Pill. As for the specific effects, he believed the Proficiency Panel would provide a direct display.
"Ten packs of Ju Yuan Ling San, one bottle of Spirit Enhancement Pill." Good Spirit Pills were hard to come by, so Jia Ren decisively paid with Spirit Stones.
Limited sale? As long as the Ju Yuan Ling San is effective, I wouldn't mind changing my disguise to come and purchase more.
Jia Ren paid two hundred and sixty Spirit Stones and left contentedly with the elixirs. He confirmed repeatedly that he was not being followed and had not attracted any unexpected troubles. He had only inquired about Mechanism Puppets but did not purchase any, never crossing any lines.
I'll just have to mine slowly. It's slow, but it's safe and steady.
